## Figure 4.
The influence of Coulomb interactions on the spectra of 〈n_{2s}. The relevant parameters are taken to be 〉V_{1} = 0.5, V_{2} = 0.1, and . (a) The spectrum of 〈n_{2s}〉 vs ϵ_{1} and ϵ_{2}. The Coulomb interactions are taken to be U_{1} = U_{2} = 1.0. (b) The spectrum of 〈n_{2s}〉 with U_{1} = 3.0 and U_{2} = 1.0. (c) The curve of 〈n_{2s}〉 vs ϵ_{2} with U_{1} = U_{2} = 3.0. The level of QD-1 is taken to be ϵ_{1} = 0 and ±0.5, respectively.
